A pickup truck's weight depends on the model, make and size of the truck. Normally, a pickup truck would weigh from 1750 lbs to 4550 lbs, but even that is just a guess since the exact numbers vary from one truck to the next. A pickup truck's weight depends on the model, make and size of the truck.
rods and cones. The photoreceptor cells of the retina. They are between the pigment epithelium and the bipolar layer of neurons. The rods contain rhodopsin, which is stimulated by light; the cones contain one of three other photopigments, which are stimulated by various wavelengths of visible light (colors).
Rods and cones are photoreceptors that are located in the retina of the eye. Rods are responsible for vision at low light levels while cones are responsible for vision at higher light levels. Therefore, rods are very sensitive to light. Rods work well at night when light is low. Cones, however, are responsible for color vision and high visual spatial acuity. Therefore, rods cannot distinguish colors. With these differences, the correct answer is: A. Rods are very sensitive to light but do not distinguish colors.
